Huacong Li

Abstract

How to design virtual instrument using LabWindows/CVI.is introduced This instrument has a friendly interface;it can achieve signal generation,signal analysis,etc.Some measurement tests were taken and the VI's result full accorded with theory result.The result proves that the function of the vibration measurement virtual instrument is achieved and the analysis results of the instrument are right.
